Australian Geology Travel Maps is a field app that displays the best available data from the government geological surveys in interactive maps created by Trilobite Solutions. It does not have any reliance on cell phone reception in the field, and uses GPS so your location is always marked on the map. Maps are downloaded to your phone when have an internet connection, and from that point on, you are independent of the internet.

The simple geology maps are rich with contextual data - including shaded relief, roads, towns, tracks, rivers, lakes, geographic names, indigenous land, national parks & provincial parks.

App development, system maintenance and user support is fully-funded by subscriptions - there is no in-app advertising and your data is absolutely PRIVATE.

Awesome App with one little fault

I used this app for the first time and it is awesome. My only complaint is that the topo maps could be better, once you zoom in past a certain point the maps go fuzzy and pixelated. Good topo maps do exist as I have them on another app. Otherwise the app is 5 stars.

This is the most comprehensive and versatile App I have found for my needs. I prospect and detect for gold all over Australia and use it to extensively research locations before I arrive at my destinations, then it’s used in the field to pinpoint these areas of interest. The Australian Geology App is so portable and has the great advantage that it can be used in those remote areas where there is no internet. Besides using this App for gold prospecting I’m constantly using it on a daily basis when I’m travelling around Australia. What a great education tool.
The developer has created the perfect App and is to be congratulated. I can thoroughly recommend it to anybody who is travelling Australia.

Brilliant & can only get better with time

I live in Victoria & detect/prospect in Vic WA SA NSW
I have traditionally used various gov’s data sets along with Google Earth Pro and a couple of other Gold Detecting APPS.

Having started using this absolutely brilliant APP, I am now able do extensive research on my desktop, laptop and I phone both at home or out in the field.

Prior to going out into the field I down load
and save Offline maps into Google Earth Pro then use the abundance of files from this Absolutely Brilliant Program and your Web Site.

Before heading back to WA when The Pandemic restrictions ease I will be out in Vic’s Golden Triangle familiarising myself further this program.

The laptop comes in very handy when used with a USB GPS.


Please keep up the great work.

Thank you Trilobite Solutions
